Day 1: Introduction day A military machine for hurling missiles, such as large stones or spears, used in ancient and medieval times.
A catapult was a large machine on wheels with a basket attached to a long wooden arm and a power source for hurling projectiles on the other. The first catapult however was invented around 400 BC in Greek town Syracus.
Day 2: Quick build
Variables dealt with are how far to pull back, how to construct the nails and which size rubber bands to use.
Force-Strength or energy as an attribute of physical action or movement.
Energy-The strength and vitality required for sustained physical or mental activity.
Day 3&4: Science investigation
The rubber bands hold potential energy and when they are released all that energy is throwing the ball with it.
Day 5&6: We built a cheap version out of rulers, markers and tape. It successfully worked.
Day 7&8: Best feature is our power and distance.
